"Politically correct" is nothing but a euphemism for "liberals" defending their golden calves(non-whites, Muslims and women).
If PC was really what you say it is, "comedians" who are overwhelming "liberals" would be completely out of business. The reason why Jon Stewart and John Oliver are so popular with "liberals" is because "liberals" are the most vulgar people in the country.
You aren't really evaluating liberals' language and political correctness based on professional comedians, are you? If that's all you got, no wonder you sometimes sound like a newly landed Martian.
"Professional" comedians or every single left wing site and media outlet, there is no real difference.
If Trump is all you got to label Republicans, you should just give up now.
Even many Democrats think the "regressive left" is the worst of the worst.
Fortunately, I don't judge all Republicans by Trump, but I do hold them accountable for making him their nominee. Comedians are supposed to shock and break the rules; it's what makes them funny. I have never heard a media outlet tout grabbing snatch. See, liberals are SENSITIVE to that shit. You should read up on the phenomenon here--there are at least two threads a day bemoaning the liberal public education brainwashing that doesn't let you say n*gger or f*ggot in polite company.
That is nothing but a pathetic strawman and pure projection.
Nobody but idiot trolls say the word "******" anymore. It is the "PC" assholes who are trying to make anti-white and anti-male terms acceptable and it is the real left and the "alt right" who support candidates like Trump to stop that shit from happening.
"Liberals" are demons who can tolerate any deplorable behavior. "Grabbing snatch" is what future idiot Democrats do for fun at "Spring Break", it is weak-sauce to them and Trump was just saying that to sound cool to Howard Stern.
Ironically if "PC" didn't exist Trump would have the entire millennial vote sewn up just with his bluster, and Hillary wouldn't have a prayer.
